Draw multiple series

[mahdiye-imanpanah]

Hi guys
I'm using Livecharts(wpf) to draw a CartesianChart with more than 10 LineSeries.
I have to draw all of the series vertically on top of each other vertically, I read all the samples and documentation in your repository but could not find the right solution.
There was a Mapping property that was the closet option I guess,
this is the way I used it:
Mapping = (logPoint, index) => new(logPoint.X, logPoint.Y + 100 ),
However, when hovering over the chart, the values are the sum of Y and 100.
I want to see the original value not the mapped one.
How can I achieve this goal???

I attached the output to this issue.

Hello, it seems that the stacked area sample is what you need:

https://livecharts.dev/docs/WPF/2.0.0-rc4/samples.stackedArea.basic

Is that enough?

I will close this for now, since this seems to be a question and not an issue with the library, please feel free to reply in the generated discussion, I will help you there.

Thanks, dear @beto-rodriguez for your response
But StackedArea is not the answer to my question.
There is a concept in charts named 'Offset'; you can change the chart's start in both the x and y axes.
I could not find anything related to this in your library.
There was just a Mapping option that when I use it the value shown in the tooltip is not correct.
For instance, I have 3 series I want to show in a cartesianChart:
The values are listed below:
1- [1 , 2 , 3, 4 , 5, 6 , 7, 8]
2- [2 , 5, 6, 8 , 9 , 1 , 4, 8]
3- [-1 , 0 , 3 , 7 , 8 , 0 , 2]

I want to draw these series on top of each other(vertically), after drawing the first, the second chart should start from the highest value in the first item which is 8 in this case, and so on.

Any help would be appreciated.
